To provide a method for manufacturing a printed matter which enables manufacture of a pressure-bonded print that achieves both high initial adhesive force and suppression of breakage when being peeled after having been stored under high temperature and high humidity.SOLUTION: A method for manufacturing a printed matter includes: a step of imparting pressure phase transition particles onto a recording medium having arithmetic average roughness Ra of 0.07 μm or more and 3.80 μm or less; a step of bonding the pressure phase transition particles to the recording medium, and forming a pressure phase transition particle layer; and a step of pressure-bonding the recording media while folding the bonded recording medium or making the bonded recording medium overlap the other recording medium. A coverage rate C of the pressure phase transition particle layer is 30% or more and 90% or less, the pressure phase transition particles contain a styrenic resin containing other vinyl monomer in a polymerization component and a (meth)acrylate resin containing 90 mass% or more of two or more kinds of (meth)acrylates in the polymerization component, the pressure phase transition particles have two or more glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature is 30°C or more.SELECTED DRAWING: None 【課題】初期の接着力が高いことと高温高湿下で保管した後に剥がした場合における破れが抑制されることとを両立する圧着印刷物を製造しうる印刷物の製造方法を提供する。【解決手段】算術平均粗さＲａが０．０７μｍ以上３．８０μｍ以下の記録媒体に圧力相転移性粒子を付与する工程と、圧力相転移性粒子を記録媒体に接着して圧力相転移性粒子層を形成する工程と、接着された記録媒体を折り重ねて又は別の記録媒体とを重ねて圧着する工程と、を有し、圧力相転移性粒子層の被覆率Ｃは３０％以上９０％以下であり、圧力相転移性粒子は、他のビニルモノマーを重合成分に含むスチレン系樹脂と、２種以上かつ９０質量％以上で（メタ）アクリル酸エステルを重合成分に含む（メタ）アクリル酸エステル系樹脂と、を含み、圧力相転移性粒子は２以上のガラス転移温度を有し、最も低いガラス転移温度と最も高いガラス転移温度との差が３０℃以上である、印刷物の製造方法。【選択図】なし
